A cyber incident response plan is a well-documented and organized set of procedures that outlines how your team detects, contains, and recovers from a security incident.

Most plans are built for organizations with dedicated security staff, defined shift coverage, and internal analysts who own the process end-to-end. SMBs rarely have that. So the plan gets written to satisfy a compliance requirement, not to reflect how the organization would actually respond at 2 a.m. on a Saturday.

The NIST incident response plan framework (now updated in SP 800-61 Rev. 3 to align with the NIST Cybersecurity Framework 2.0) remains the most widely referenced standard for structuring how organizations prepare for, detect, and recover from security incidents.

NIST divides the incident response process into six phases: Preparation, Detection and Analysis, Containment, Eradication, Recovery, and Post-Incident Activity.

Where SMBs run into trouble is assuming they can execute all six phases internally. Preparation is manageable. But Detection and Analysis? That requires continuous monitoring and the expertise to distinguish a real threat from noise. IBM reports the average breach takes 181 days to identify and another 60 days to contain. That's 241 days of an attacker inside your environment, and most of those days fall outside business hours.

For SMBs without a dedicated security team, these are the three components most likely to be missing from the plan entirely:

• After-hours coverage: Who responds when your team isn't in the office? If your plan assumes business hours, it's already incomplete.

• SOC coordination procedures: If you work with a managed SOC, your plan needs to specify exactly how information flows between the SOC and your internal team. What does the SOC escalate? To whom? Through what channel?

• Threshold definitions: When does suspicious activity become an incident? Who makes that call—your team or the SOC?

An incident response plan is the overarching framework, while a playbook is a step-by-step guide for a specific incident type—ransomware, business email compromise, or credential theft.

Think of your IRP as the operational constitution and playbooks as the legislation. You need both. The plan sets the rules of engagement; the playbooks tell your team (and your SOC) exactly what to do when a specific scenario unfolds. A managed SOC often brings pre-built playbooks for common attack types.

A SOC incident response plan defines not just what your internal team does during an incident, but how that team and your managed SOC operate as a single coordinated unit—with clear handoffs, shared thresholds, and no ambiguity about who owns what decision.

The SOC incident response process begins the minute you partner with them, not when you call them during an incident. What that means for your plan: define the relationship explicitly. Spell out what the SOC owns versus what your team owns, establish the escalation path, and document the communication channel you'll use during an active incident.

Knowing how to create an incident response plan is one thing, but building one that holds up when your managed SOC flags suspicious lateral movement is another. Understanding the incident response plan steps before an attack happens is what separates a team that contains damage quickly from one that's still figuring out who to call.

Start with scope and stakeholders. Then define your incident categories and severity thresholds. Build your escalation tree and include your managed SOC explicitly.

For SMBs without a full security team, SOC as a service with incident response built in closes the gap that most standalone IRPs quietly ignore—continuous monitoring, after-hours triage, and an escalation path that doesn't depend on someone checking their phone.

IBM found that organizations detecting breaches internally—rather than being notified by an attacker—shortened their breach lifecycle by 61 days and saved nearly $1M in costs. Tabletop exercises are how you build that internal detection muscle.

Run at least one tabletop a year. Include your managed SOC in the exercise, because if you haven't practiced the handoff together, you don't actually know how it works. After every tabletop, update the plan.

The IRP that works is the one built around your actual reality and not the reality of a fully-staffed enterprise security team.

For most SMBs, that means pairing your IRP with a managed SOC that can cover the gaps your internal team can't. Huntress provides 24/7 SOC coverage alongside managed endpoint, identity, and email protection, so your incident response plan has the operational backbone to actually work when it matters.
